As has been shown in previous researches the fatty acids in human blood exist, as glycerides, cholesterol esters, soaps, or as free acids; they are also represented as a radical of lecithin and the phosphatide groups. Their content varies in continued starvation, fat absorption, anesthesia, certain pathological conditions, et’c., as recently reported and confirmed in a series of papers by B1oor...

The membrane lipid and fatty acid compositions of red blood cells from a paramyotonia patient were investigated. Cholesterol and total phospholipid contents in paramyotonia were not different from control. Only the sphingomyelin content was lower, and thus the molar ratio of phosphatidylcholine/sphingomyelin was higher than normal. The major abnormality concerned the fatty acid pattern. In all ...

Plant leaf systems have been incubated under various conditions with uniformly labeled oleic acid, and the breakdown products identified by gas-liquid chromatography. Young green leaves of the castor plant (Ricinis gibsonii) and of the field pea plant (Pisum sutiuum) catabolize oleic acid by an oxygen-requiring pathway to heptadec-8-enaI which is then dehydrogenated by an NAD-coupled mechanism ...

The study was conducted to investigate the fatty acid profile of intramuscular fat in longissimus lumborum (LL) of three genotypic groups: Qazvinian native (Q, n=10), crossbred Qazvinian native × Saanen breed (QS, n=10) and backcrossed Qazvinian native × Saanen breed (QSS, n=9) male kids.All of kids were weaned at 75-days-old and then fed with a diet consisted of concentrate (70%) and alfalfa h...

The fatty acid composition of the phospholipids from the desiccation-tolerant moss Tortula ruralis (Hedw.) Gaertn, Meyer and Scherb and the desiccation-intolerant moss Cratoneuron filicinum has been determined. No changes in composition occur in either moss as a consequence of rapid drying, but, after slow drying, there is a decline in some unsaturated fatty acids. Upon rehydration of T. rurali...

ATP-binding cassette transporters (ABC) G1 and ABCA1 are membrane cholesterol transporters and have been implicated to mediate cholesterol efflux from cells in the presence of high density lipoproteins and its major protein constituent apolipoprotein A-I, respectively. We previously demonstrated that unsaturated fatty acids suppress the stimulatory effects of oxysterols and retinoids on ABCA1 g...

The mitochondrial beta-oxidation system is one of the central metabolic pathways of energy metabolism in mammals. Enzyme defects in this pathway cause fatty acid oxidation disorders. To elucidate the role of 2,4-dienoyl-CoA reductase (DECR) as an auxiliary enzyme in the mitochondrial beta-oxidation of unsaturated fatty acids, we created a DECR-deficient mouse line. In Decr(-/-) mice, the mitoch...
